CHERUBINO MCARTHUR, OF HUDSON,I NEW YORK.

MOTOR.

SPECIFICATIONforming part'of Letters Patent No. 761,531, dated May 31, 1904.

Application filed January 29, 1903.

To all whom t `may concern:

Be it known that I, OHERUBINO MOARTHUR, a citizen ofthe United States, residing at Hudson, in the county of Columbia and State of New York, have invented anew and useful Motor, of which the following is a specification.

This invention relates to devices for the transmission of motion, for instance, from a springer a weight to the machinery to be operated; and it has for its object to provide a' device of this class which mayy be simply land easily constructed and operated and which shall be provided with means coperating with the main motor-'wheel for the purpose of stopping said wheel and for the purpose lof starting the same when released from the stopping mechanism, thus enabling said main motorwheel or power-wheel tobe started or stopped, as may be required, thereby avoiding unnecessary expenditure of power.

With these and other ends in view, all tendshall possess superior advantages in point of simplicity, durability, and general eiiciency, my invention consists in the improved construction, arrangement, and combination of parts which will be hereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of a weight-motor embodying my invention. Fig. 2 is a plan view. Fig. 3 is/an end elevation of the same.

Corresponding parts in the several iigures are kindicated by similar numerals'of reference.

In the accompanying drawings I have shown my invention applied to a motor operated by a weight,with the understanding, however, that the'parts which constitute my invention may equally well be applied to a motor driven by a spring or springs or in any other well-known manner.v 10 designates a main drive-shaft any approved form and of suitable-height to erating-weight, or the said weight may be arranged to operate in a well or excavation, as the conditions or circumstances may require. The shaft 10 is provided with a power-transmitting wheel 12, the rim of which is pro- Serial No. 141,;063. (No model.)

vided on the edge thereof with suitably-spaced equidistant notches 13, adapted to be engaged bythe stop mechanism to be hereinafter more fully described. VThe power-wheel may be employed to transmit power in any suitable'v i manner, and for the purpose of illustration sprocket-teeth 14. have been shown formed upon its rim, by which the power may be transmitted by a chain 15 to a sprocket-pin- .ion 16 on the counter-shaft 17, from whence the motion will be transmitted in any suitable desired results, it will be understood that any desired kind of machinery may be operated from the shaft 10 and that any required 6p manner in any desired direction and for any desired purpose. Whilethe arrangement th'us shown is operative and will accomplish theY speed or power may be attached by using av a transmission-train of wheels properly proportioned to the work required.

The shaft 10 has in this instance a looselymounted drum 21, supportingacable 22. This cable vcarries a weight 23 of suitable size to produce the requisite power or speed.'\ The drum .is provided with a ratchet-disk 25 engaging a spring-actuated pawl 26, pivotally connected with the power-wheel, which will thereby be connected with the drum, while` the latter may whenever-'necessary be wound` to elevate the weight 23. For this purpose I prefer to provide the drum with a sprocketwheel 29, over which a chain 30 runs from a i sprocket-pinion 3l on -a shaft 32, the latteny having a square end 33, upon which may be mounted a winding-crank to provide for the winding up of the cable and weight. It is obvious that-without departing from my invention any other suitable means may be employed for the purpose of winding the drum i' will draw the bar longitudinally and release it from engagement with the power-wheel and likewise release the latter.

The bar is provided with a recess 38, and disposed at right angles to the bar 35 and held in yieldable engagement within the recess by a spring 39 is a lock-bar 40, the recess being so placed that when the bar 40 is in its operative position the bar 35 will be held out of engagement with the wheel 12 by the bar 40 engaging the recess by its inclined end 42.

The bar 40 will be operated electrically, as by a solenoid-magnet, (indicated at 41,) which when properly connected and energized will draw the lock-bar longitudinally and release it from engagement with the stop-bar and permit the spring 36 to throw it into the path of the cavities 13 and stop the further movement of the power-wheel. Then when the currents through the magnets are broken the springs will restore the bars to their former positions. By this simple arrangement when it is desired to stop the movement lof the power-wheel it -is only necessary to close a circuit through the magnet 41 and when it is desired to start the power-wheel it is only necessary to close a circuitthrough the magnet 37, as will be obvious.

The circuit-operating means, Ait will be understood,may be arranged at any desired point, and as they form no part of the present invention they are-not illustrated.

Any of the ordinary circuit closing or opening devices may be employed, and I do not,

therefore, wish to be limited to any specific mechanism for accomplishing the desired resu ts.

The operation and advantages of my invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. It is well known, of course, that weight motors are commonly employed for the purpose of operating light machinery of all kinds; but one dificulty usually experienced in connection with this class of motors has been that of starting and stopping them in a very certain and positive manner, and the failure to do so has frequently resulted in serious loss of power.

By my improvement the means for starting the machine and for stopping the rotation of the power-wheel are applied directly to the latter, said power-wheel being specially constructed, as hereinbefore described, to coperate with the starting and stopping means.

By the special construction of the powerwheel I refer to the providing of the same with the peripheral notches in the rim thereof, which will be automatically engaged by the spring-actuated stop-bar 35 whenever the spring-actuated tri p-bar 40 is disengaged from the recess 38 in said stop-bar. While I have herein described the stop-bar 35 and the tripbar 40 as being electrically operated, it is obvious that they may within the scope of my invention be operated in any other convenient manner, it being simply necessary to withdraw the stop-bar 35 from engagement with the notches 13 of the power-wheel in order to release the latter, said stop-bar beingretained in inactive position by means of the springactuated trip-bar 40. On the other hand, in order to stop the rotation of the power-wheel it is only necessary to release the trip-bar 40 from engagement with the notch 38 in the stop-bar, when the spring actuating the latter will instantly and automatically force it into engagement with one of the notches 13 of the power-wheel, thus instantly and effectively stopping the rotation thereof.

My improved weight-motor, it will be observed, is of extremely simple construction, and it may be put up and operated at a triliing expense.

I have in the foregoing described a simple and preferred form of my invention; but l desire it to be understood that I do not limit myself with regard to the structural details of the same, but reserve the right to any changes, alterations, and modifications which may he resorted to within the scope of my invention and without departing from the spirit or sacrificing the utility of the same.

Having thus described my invention, l claim- In a device of the class described, a powerwheel having spaced notches in the rim thereof, a spring-actuated stop-bar adapted to engage the notches in the rim of the powerwheel and provided with a recess, a springactuated trip adapted to engage said recess,

and means for independently reciprocating the said stop and trip to start or stop the rotation of the power-wheel.

In testimony that I claim the foregoing as my own I have hereto aiiixed my signature in the presence of two witnesses.
